Overview

The material in this documentation pertains to a QLogic OFED cluster. A cluster is defined as a collection of nodes, each attached to an InfiniBand™-based fabric

through the QLogic interconnect. The nodes are Linux-based computers, each having up to 16 processors.

The QLogic HCAs are InfiniBand 4X. The Double Data Rate (DDR) QLE7240 and QLE7280 adapters have a raw data rate of 20Gbps (data rate of 16Gbps). For the Single Data Rate (SDR) adapters, the QLE7140 and QHT7140, the raw data rate is 10Gbps (data rate of 8Gbps). The QLE7240 and QLE7280 can also run in SDR mode.

The QLogic adapters utilize standard, off-the-shelf InfiniBand 4X switches and cabling. The QLogic interconnect is designed to work with all InfiniBand-compliant switches.

NOTE:

reference.

If you are using the QLE7240 or QLE7280, and want to use DDR mode, then DDR-capable switches must be used.

1-2 Preliminary IB0056101-00 G.02

Draft

QLogic OFED OpenFabrics software is interoperable with other vendors’ InfiniBand Host Channel Adapters (HCAs) running compatible OpenFabrics releases. There are several options for subnet management in your cluster:

 Use the embedded Subnet Manager (SM) in one or more managed switches

supplied by your InfiniBand switch vendor.

 Use a host-based Subnet Manager. QLogic provides one, HSM, as a part of

the InfiniBand fabric Suite download.

 Use the Open source Subnet Manager (OpenSM) component of

OpenFabrics.

Interoperability

QLogic InfiniPath participates in the standard InfiniBand subnet management protocols for configuration and monitoring. Note that:

 InfiniPath OpenFabrics (including Internet Protocol over InfiniBand (IPoIB))

is interoperable with other vendors’ InfiniBand HCAs running compatible OpenFabrics releases.

Introduction

Interoperability

 The QLogic MPI stack is not interoperable with other InfiniBand HCAs and

Target Channel Adapters (TCAs). Instead, it uses an InfiniBand-compliant, vendor-specific protocol that is highly optimized for QLogic MPI and for MPI over verbs.

NOTE:

See the OpenFabrics web site at www.openfabrics.org on the OpenFabrics Alliance.

Installation of the QLE7240, QLE7280, QLE7140, QHT7040, or QHT7140 in a 1U or 2U chassis requires the use of a riser card. See Figure 4-4 for an illustration of a PCI Express (PCIe) slot in a typical motherboard. See Figure 4-7 for an illustration of an HTX slot for a typical Opteron motherboard.

The motherboard vendor is the optimal source for information on the layout and use of HyperTransport and PCI Express-enabled expansion slots on supported motherboards.

The QLE7240, QLE7280, and QLE7140 are the model numbers for the adapters that ship in the standard PCI Express half-height, short-form factor. These adapters can be used with either full-height or low-profile face plates.

The QHT7040 is the model number for the adapter that shipped in the HTX full-height factor. The HTX low-profile form factor is referred to as the QHT7140. It is the same as the QHT7040, except for its more compact size. In either case, the adapter is backward and forward compatible for the motherboards in which it is supported. The QHT7040 and QHT7140 HTX adapters are collectively referred to as the QHT7140 unless otherwise stated.

Motherboards with HTX connectors

Cabling and Switches

The cable installation uses a standard InfiniBand (IB) 4X cable. Any InfiniBand cable that has been qualified by the vendor should work. For SDR, the longest passive copper IB cable that QLogic has currently qualified is 20 meters. For DDR-capable adapters and switches, the DDR-capable passive copper cables cannot be longer than 10 meters. Active cables can eliminate some of the cable length restrictions.

InfiniBand switches are available through QLogic.

NOTE:

If you are using the QLE7240 or QLE7280 and want to use DDR mode, then DDR-capable switches must be used.

The copper cables listed in Table 4-2 are available from QLogic:

for more information.

Configuring the BIOS

To achieve the best performance with QLogic adapters, you need to configure your BIOS with specific settings. The BIOS settings, which are stored in non-volatile memory, contain certain parameters characterizing the system. These parameters may include date and time, configuration settings, and information about the installed hardware.

This setting is required:

 Advanced Configuration and Power Interface (ACPI) BIOS option must be

enabled.

For more information, see “Enable Advanced Configuration and Power Interface

(ACPI)” on page A-2and the Troubleshooting section of the QLogic HCA and

QLogic OFED Software Users Guide.

Some other BIOS settings can be adjusted for better adapter performance. See

“Adapter and Other Settings” on page 7-1.

For specific instructions about BIOS settings, follow the hardware documentation that came with your system.

NOTE:

The x86 Page Attribute Table (PAT) mechanism that allocates write-combining (WC) mappings for the PIO buffers has been added and is now the default. This was previously a BIOS setting. For more information, see “Write Combining” on page B-1.

Safety with Electricity

Observe these guidelines and safety precautions when working around computer hardware and electrical equipment:

 Locate the power source shutoff for the computer room or lab where you are

working. This is where you will turn OFF the power in the event of an emergency or accident. Never assume that power has been disconnected for a circuit; always check first.

 Do not wear loose clothing. Fasten your tie or scarf, remove jewelry, and roll

up your sleeves. Wear safety glasses when working under any conditions that might be hazardous to your eyes.

 Shut down and disconnect the system’s power supply from AC service

before you begin work, to insure that standby power is not active. Power off all attached devices such as monitors, printers, and external components. Note that many motherboards and power supplies maintain standby power at all times. Inserting or removing components while standby is active can damage them.

Hardware Installation

This section contains hardware installation instructions for the QLE7240, QLE7280, QLE7140, QHT7040, and QHT7140.

Hardware Installation for QLE7240, QLE7280, or QLE7140 with PCI Express Riser

Installation for the QLE7240, QLE7280, and QLE7140 is similar. The following instructions are for the QLE7140, but can be used for any of these three adapters.

Most installations will be in 1U and 2U chassis, using a PCIe right angle riser card. This results in an installation of the adapter that is parallel to the motherboard. This type of installation is described first. Installation in a 3U chassis is described in “Hardware Installation for the QHT7140 Without an HTX Riser” on page 4-16.

Installing the QLogic QLE7140 in a 1U or 2U chassis requires a PCIe right angle riser card.

A taller riser card can be used if necessary. The QLE7140 can connect to any of the standard compatible PCI Express riser cards.

Dual Adapter Installation

If you have a motherboard with dual PCIe slots, dual adapters can be installed. The adapters must match. For example, on a motherboard with two x16 slots, dual QLE7280 adapters can be installed, but not a QLE7240 adapter and a QLE7280 adapter. Check the design of your motherboard to see how riser cards can be used.

Follow the instructions in “Installation Steps” on page 4-9.

See the Using MPI section in the QLogic HCA and QLogic OFED Software Users Guide for information on using the IPATH_UNIT environment variable to control which HCA to use.

Installation Steps

To install the QLogic adapter with a PCIe riser card:

1. The BIOS should already be configured properly by the motherboard manufacturer. However, if any additional BIOS configuration is required, it will usually need to be done before installing the QLogic adapter. See

“Configuring the BIOS” on page 4-4.

2. Shut down the power supply to the system into which you will install the QLogic adapter.

3. Take precautions to avoid electrostatic damage (ESD) to the cards by properly grounding yourself or touching the metal chassis to discharge static electricity before handling the cards.

This section provides instructions for installing QLogic OFED 1.4, which includes QLogic InfiniPath and the OpenFabrics software. The software includes drivers, protocol libraries, QLogic’s implementation of the MPI message passing standard, associated utilities, and example programs, including benchmarks. A complete list of the provided software is in “Software Components” on page 2-4.

Cluster Setup

Information on clusters, supported distributions and kernels, and environment setup is provided in “Types of Nodes in a Cluster Environment” on page 5-1,

“Supported Linux Distributions” on page 5-1, and “Distribution Identifiers” on page 5-2.

Types of Nodes in a Cluster Environment

In a cluster environment, different nodes can be used for different functions, such as launching jobs, developing software, or running jobs. The nodes are defined as follows:

 Front end node. This node launches jobs.

 Compute node. This node runs jobs.

 Development or build node. These are the machines on which examples

or benchmarks can be compiled.

Any machine can serve any combination of these three purposes, but a typical cluster has many compute nodes and just a few (or only one) front end nodes. The number of nodes used for development will vary. These node names are used throughout this guide.

Supported Linux Distributions

The QLogic interconnect runs on AMD™ Opteron™ and 64-bit Intel Xeon systems

running Linux versions for InfiniPath and OpenFabrics are listed in Table 5-1.

The kernels are the ones that shipped with the distributions. All are for the x86_64 architecture.

Setting Up Your Environment

Used On

Keep the following in mind when setting up the environment:

 The runtime and build environments must be the same. Compatibility

between executables built on different Linux distributions cannot be guaranteed.

 You will need Administrator privileges on your machine(s).

 If using the rpm install method, make sure that all previously existing (stock)

OpenFabrics RPMs are uninstalled. See “Uninstalling InfiniPath and

OpenFabrics RPMs” on page 5-24 for more information on uninstalling. The

Installer tool will uninstall previous RPMs automatically before upgrades.

Install QLogicIB-Basic with the Installer Tool

The Installer tool has a Text User Interface (TUI) that affords easy installation of the software. Use this method if you have downloaded the QLogic-IB-Basic package. This method is suitable for use on small clusters.

1. Use the Downloads tab on the QLogic web site to locate your adapter model.

http://www.qlogic.com

Download the QLogicIB-Basic tar file for your distribution to a directory that will not be deleted upon reboot. Then unpack the tar file:

$ tar zxvf <QLogicIB-Basic>.<version>.tgz

The tar command creates a directory based on the tar file name and places the RPMs and other files in this directory.

Install QLogicIB-Basic with the Installer Tool

Open SM (1) should only be installed on one node in the cluster where it will be used. If desired, Type 1 for Open SM.

7. Finally, type p to start the installation.

The installer will uninstall older OFED RPMs, and then will ask for input for a series of operations. You can accept the defaults, by pressing <Enter>. Take note of the following cases:

Install MPI with prefix compatible with mpi-selector (/usr/mpi/qlogic) [y]: y

This default allows you to use the mpi-selector to choose between different MPI implementations.

If you type y, make sure, after installation, that the environment variable $MPICH_ROOT is set to the same prefix that is used here (/usr/mpi/qlogic). When set, the $MPICH_ROOT variable allows QLogic MPI to correctly locate header and library files for MPI compilation and running parallel jobs. Typing n will cause QLogic MPI to be installed in the default /usr.

The next case is:

Configure OFED IP over IB IPV4 addresses now? [n]:

Answer y if the IB IPV4 addresses and netmasks are available, and you want to enter them now. Answer n if the IB addresses are not available or you want to add them later. IPoIB can be configured manually by following the instructions for “Configuring the IPoIB Network Interface” on page 6-2.

Finally, QLogic recommends you answer n to the following:

Enable QLogic SRP (qlgc_srp) to autostart? [y]: n

Enable OFED SRP (openibd) to autostart? [y]: n

Further instructions for using SRP are given in “SRP” on page 6-4.

8. Once the install has completed, quit the installer by typing x until you have exited. After exiting, rebooting the machine is recommended.

NOTE:

If you want support for 32 bit programs, you can install the 32-bit libraries on a 64-bit system like this:

# ./INSTALL --32bit

The Installer can also be used as a command-line interface (CLI). There are numerous options for installation/upgrade/uninstallation/autostart of all the available components. Here are the available options:

About rpm Installation

Linux distributions of QLogic OFED (InfiniPath and OpenFabrics) software can be installed from binary RPMs. RPM is a Linux packaging and installation tool used by Red Hat, SUSE, and CentOS.

Instructions given below are for a single node. Parallel command starters can be used for installation on multiple nodes. The Yellowdog Updater, Modified (YUM) may also be used for installation. However, these subjects are beyond the scope of this document.

Software Installation Using rpm to Install InfiniPath and OpenFabrics

RPMs contain config files. Your current config files will not be overwritten when new RPMs are installed. New config files will contain the suffix .rpmnew and can be found in /etc/sysconfig and /etc/infiniband. Check the new files to see if there is anything you want to add to your standard config files

Please note:

 For convenience, QLogic recommends that the same set of RPMs are

installed on all nodes (with the exception of OpenSM). Omitting the *-Static/* and *-Debuginfo/* RPMs is recommended. Use the */32bit/* RPMs only if you need them. Some RPMs are optional depending on which type of node is being used. To see which RPMs are required or optional for each type of node, according to its function as a compute node, front end node, development machine, or Subnet Manager (SM), see Appendix D “Package

Descriptions”.

(Another way is to put the RPMs in a directory that is accessible (e.g., via Network File System (NFS)) to every node.)

NOTE:

If you wish to use the mpi-selector to switch between QLogic MPI and other MPI implementations, you need to install QLogic MPI in

an alternate location, consistent with that of the other MPIs. Skip to Step 4.

3. To install

rpm -Uvh InfiniPath/*.rpm InfiniPath-MPI/*.rpm \

InfiniPath-MPI/32bit/mpi-frontend-*.rpm \

InfiniPath-Devel/*.rpm Documentation/*.rpm OtherMPIs/*.rpm \

OpenFabrics/*.rpm OpenFabrics-Devel/*.rpm \

OtherHCAs/*.rpm OtherHCAs-Devel/*.rpm

Note that you need to install the InfiniPath-MPI/32bit/mpi-frontend-*.rpm even if you do not plan to use any other 32-bit RPMs. However, you can add the other 32bit subdirectories to the rpm command, if you need 32-bit support.

Install the OpenSM RPM only if you do not plan to use a switch-based or host-based SM. The OpenSM RPM is normally installed on the node where it will be used. If installed, it is off by default. This behavior can be modified. See “OpenSM” on page 6-3 for more information.

To add Open SM, add this command:

Finally, install the prefixed QLogic-MPI RPMs in /usr/mpi/qlogic:

rpm -Uvh --prefix /usr/mpi/qlogic QLogic-MPI-prefixed/*.rpm

The desired prefix should be made available in the $MPICH_ROOT environment variable, either by global shell configuration files or through third-party environment management utilities such as mpi-selector or the Environment Modules. This allows QLogic MPI to correctly locate header and library files for MPI compilation and running parallel jobs. See the QLogic HCA and QLogic OFED Software Users Guide for details.

5. Reboot.

RPM Organization

:The complete RPM directories are organized as follows. Note that the suggested installation does not include all possible RPM directories. Install the files in the *-Devel directories if you are going use source code to do development work. The *-Debuginfo directories contain debug information and possibly source code, which may be useful for testing, debugging, and developing applications. The *-Static directories contain the static versions of the libraries, which can be used in place of the dynamic libraries when compiling and linking.

Rebuilding or Reinstalling the kernel-ib Driver with rpm After a Kernel Upgrade

If you upgrade the kernel, then you must reboot and then rebuild or reinstall the InfiniPath kernel modules (drivers).

To rebuild the drivers, do the following (as root):

# cd /usr/src/qlogic_ib/kernel-ib-<version>

# ./make-install.sh

# /etc/init.d/openibd restart

An alternative method is to reinstall the InfiniPath kernel modules and then restart the InfiniPath service. Type (as root):

# rpm -U --replacepkgs kernel-ib-*

# /etc/init.d/openibd restart

Rebuilding the kernel-ib Driver on an Unsupported Distribution or an Unsupported Distribution/Kernel Pair

If the rpm install can’t correctly determine the underlying distribution/kernel combination, you will see a warning message. This can occur if you try to install on an unsupported distribution or an unsupported distribution/kernel pair.

Using the override may not result in a buildable or working driver if your distribution/kernel combination is not similar enough to a tested and supported distribution/kernel pair.

Install QLogic OFED Using Rocks

Rocks is a distribution designed for managing clusters from the San Diego Supercomputer center (SDSC).

Rocks is a way to manage the kickstart automated installation method created by Red Hat. By using the Rocks conventions, the installation process can be automated for clusters of any size. A Roll is an extension to the Rocks base distribution that supports different cluster types or provides extra functionality.

QLogic extends the normal Rocks compute node appliance xml file by adding two functions: one function installs the InfiniPath software, and the other function loads the drivers after kickstart reboots the machine.

Install Frontend and Compute Nodes

Rocks is based on a set of "kickstart graphs" (xml files) that tell the frontend node which pieces need to be installed on which type of compute nodes. The frontend node installs from local RPMs, and the compute nodes then collect the RPMs from the frontend. You will first have to install a Rocks frontend node, if you don’t already have one.

To install a Rocks frontend node:

1. Use the Downloads tab on the QLogic web site to locate your adapter model.

http://www.qlogic.com

2. Download the InfiniPath roll (.iso image) for your distribution and burn the .iso image to a CD.

3. Download the required rolls from the Rocks web site:

http://www.rocksclusters.org

a. Follow the links to get the following .iso images that can be burned to a

CD or DVD:

Kernel/Boot Roll

Core Roll

OS Roll (Disk 1 & 2)

Note that you may also need updates; look for the latest files with the service-pack prefix. Make sure you downloaded the .iso images correctly; verify by checking the md5 checksum from the web site.

b. Burn the .iso image(s) to a CD(s) or DVD.

4. Build the frontend node with the above .iso images (step 2) from the Rocks web site:

a. Insert the Kernel/Boot Roll CD into your frontend machine. After the

frontend boots off the CD, follow the instructions on the screen. Insert the OS Rolls and any other of the Rocks rolls you need when prompted.

b. To install the InfiniPath roll, put the InfiniPath CD into the drive when

prompted if you wish to install additional rolls. Follow the instructions. For more details, see the Rocks installation documentation on the Rocks web site:

http://www.rocksclusters.org

5. Install the compute nodes. Login to the frontend node as root, and run the command:

# insert-ethers

This runs a program which captures compute node DHCP requests and puts the information into the Rocks MySQL database. Follow the instructions on the Rocks web site:

http://www.rocksclusters.org

6. Once Rocks is up and running, test the rocks cluster according to your own testing procedures.

NOTE:

You can also get rolls directly from Platform OCS or ClusterCorp. The web sites are:

http://my.platform.com/products/platform-ocs http://www.clustercorp.com/

Rocks Installation on an Existing Frontend Node

If the frontend node has already been installed, you can add the InfiniPath roll to the repository on the head node, update the master graph.xml, and re-install all the compute nodes. Use these instructions. You must be root.

6 Configuring Drivers and

Services

This section provides instructions for configuring and using the drivers and services available with QLogic OFED 1.4.

InfiniPath and OpenFabrics Driver Overview

The InfiniPath ib_ipath module provides low level QLogic hardware support, and is the base driver for both MPI/PSM programs, and general OpenFabrics

protocols such as IPoIB and SDP. The driver also supplies the Subnet Management Agent (SMA) component.

Optional configurable OpenFabrics components and their default settings at startup are:

 IPoIB network interface. Required for TCP/IP networking for running

Ethernet traffic over the InfiniPath link. It is not running until it is configured.

 VNIC. It is not running until it is configured.

 OpenSM. It is disabled on startup. You can either install it on only one node,

or disable it on all nodes except where it will be used as an SM.

 SRP (OFED and QLogic modules). SRP is not running until the module is

loaded and the SRP devices on the fabric have been discovered.

 MPI over uDAPL (can be used by Intel MPI or HP-MPI). IPoIB needs to be

configured before MPI over uDAPL can be set up.

Other optional drivers can now be configured and enabled, as described in

“OpenFabrics Drivers and Services Configuration and Startup” on page 6-1.

Complete information about starting, stopping, and restarting the InfiniPath services are in “Managing the InfiniPath Driver” on page 6-15.

OpenFabrics Drivers and Services Configuration and Startup

IPoIB, VNIC, OpenSM, SRP, and MPI over uDAPL configuration and startup is explained in more detail in the following sections.

Configuring Drivers and Services OpenFabrics Drivers and Services Configuration and Startup

Configuring the IPoIB Network Interface

The following instructions show you how to manually configure your OpenFabrics IPoIB network interface. This example assumes that you are using

your shell, all required InfiniPath and OpenFabrics RPMs are installed, and your startup scripts have been run (either manually or at system boot).

For this example, the IPoIB network is 10.1.17.0 (one of the networks reserved for private use, and thus not routable on the Internet), with a /8 host portion, and therefore requires that the netmask be specified.

This example assumes that no hosts files exist, the host being configured has the IP address 10.1.17.3, and DHCP is not used.

NOTE:

Instructions are only for this static IP address case. Configuration methods for using DHCP will be supplied in a later release.

sh or bash as

1. Type the following commands (as root):

# ifconfig ib0 10.1.17.3 netmask 0xffffff00

2. To verify the configuration, type:

# ifconfig ib0

The output from this command will be similar to this:

ib0 Link encap:InfiniBand HWaddr

64 bytes from 10.1.17.7: icmp_seq=0 ttl=64 time=0.073 ms (DUP!)

The IPoIB network interface is now configured.

4. Restart (as root) by typing:

# /etc/init.d/openibd restart

NOTE:

 The configuration must be repeated each time the system is rebooted.  IPoIB-CM (Connected Mode) is enabled by default. The setting in

/etc/infiniband/openib.conf is SET_IPOIB_CM=yes. To use

datagram mode use SET_IPOIB_CM=no.

OpenSM

OpenSM is an optional component of the OpenFabrics project that provides a subnet manager for InfiniBand networks. This package can be installed on all

machines, but only needs to be enabled on the machine in the cluster that will act as a subnet manager. You do not need to use OpenSM if any of your InfiniBand switches provide a subnet manager, or if you are running a host-based SM.

If you are using the Installer tool, you can set the OpenSM default behavior at the time of installation.

If you are using the rpm install method, note that after installing the opensm package, OpenSM is configured to be off after the next machine reboot. It only needs to be enabled on the node that acts as the subnet manager, so use the

chkconfig command (as root) to enable it on the node where it is to run:

# chkconfig opensmd on

The command to disable it on reboot is:

# chkconfig opensmd off

You can start opensmd without rebooting your machine by typing:

# /etc/init.d/opensmd start

IB0056101-00 G.02 Preliminary 6-3

Draft

Configuring Drivers and Services OpenFabrics Drivers and Services Configuration and Startup

You can stop opensmd again like this:

# /etc/init.d/opensmd stop

If you want to pass any arguments to the OpenSM program, modify the following file, and add the arguments to the OPTIONS variable:

/etc/init.d/opensmd

For example:

# Use the UPDN algorithm instead of the Min Hop algorithm. OPTIONS="-R updn"

For more information on OpenSM, see the OpenSM man pages, or look on the OpenFabrics web site.

SRP

SRP stands for SCSI RDMA Protocol. It was originally intended to allow the SCSI protocol to run over InfiniBand for Storage Area Network (SAN) usage. SRP

interfaces directly to the Linux file system through the SRP Upper Layer Protocol. SRP storage can be treated as another device.

In this release, two versions of SRP are available: QLogic SRP and OFED SRP. QLogic SRP is available as part of the QLogicIB-Basic*, Rocks Roll, and Platform OCS downloads.

It is not available as a part of the RPM downloads.

SRP has been tested on targets from Engenio™ (now LSI Logic

NOTE:

Using QLogic SRP

If you have installed QLogic SRP as part of the QLogicIB-Basic download, you will need to configure it according to the steps shown in the QLogic ULP and Tools

Reference Guide (OFED+ Users Guide).

Using OFED SRP

To use OFED SRP, follow these steps:

1. Add the line SRP_LOAD=yes to the module list in

Configuring and Administering the VNIC Interface

The VirtualNIC (VNIC) Upper Layer Protocol (ULP) works in conjunction with firmware running on Virtual Input/Output (VIO) hardware such as the SilverStorm Ethernet Virtual I/O Controller (EVIC™) or the InfiniBand/Ethernet Bridge Module for IBM

The VNIC driver along with the QLogic EVIC’s two 10 Gigabit ethernet ports, enables Infiniband clusters to connect to Ethernet networks. This driver also works with the earlier version of the I/O Controller, the VEx.

The QLogic VNIC driver creates virtual Ethernet interfaces and tunnels the Ethernet data to/from the EVIC over InfiniBand using an InfiniBand reliable connection.

The virtual Ethernet interface supports any Ethernet protocol. It operates normally like any other interface--ping, ssh, scp, netperf etc.

The VNIC interface must be configured before it can be used. To do so, perform the following steps:

BladeCenter®, providing virtual Ethernet connectivity.

1. Discover the EVIC/VEx Input/Output Controllers (IOCs) present on the fabric using ib_qlgc_vnic_query. For writing the configuration file, you will need information about the EVIC/VEx IOCs present on the fabric, such as

2. Create the VNIC interfaces using the configuration file:

/etc/infiniband/qlgc_vnic.cfg.

Look at the qlgc_vnic.cfg.sample file to see how VNIC configuration files are written. It can be found with the OFED documentation, or in the qlgc_vnictools subdirectory of the QLogicIB_Basic download. You can use this configuration file as the basis for creating a configuration file by replacing the Destination Global Identifier (DGID), IOCGUID, and IOCSTRING values with those of the EVIC/VEx IOCs present on your fabric.

QLogic recommends using the DGID of the EVIC/VEx IOC, as it ensures the quickest startup of the VNIC service. When DGID is specified, the IOCGUID must also be specified. For more details, see the qlgc_vnic.cfg sample file.

3. Edit the VirtualNIC configuration file, /etc/infiniband/qlgc_vnic.cfg. For each IOC connection, add a CREATE block to the file using the following format:

{CREATE; NAME="eioc2";

PRIMARY={IOCGUID=0x66A0130000105; INSTANCE=0; PORT=1; }

SECONDARY={IOCGUID=0x66A013000010C; INSTANCE=0; PORT=2;}

}

NOTE:

The qlgc_vnic.cfg file is case and format sensitive.

Do not create EIOC names with similar character strings (e.g., eioc3 and eioc30). There is a limitation with certain Linux operating systems that cannot recognize the subtle differences. The result is that the user will be unable to ping across the network.

b. Format 2: Defining an IOC using the IOCSTRING. Defining the IOC

using the IOCSTRING allows VIO hardware to be hot-swapped in and out of a specific slot. The host attempts to connect to the specified IOC (1, 2, or 3) on the VIO hardware that currently resides in the specified slot of the specified chassis. Use the following format to allow the host to connect to a VIO hardware that resides in a specific slot of a specific chassis:

{CREATE;

NAME="eioc1";

IOCSTRING="Chassis 0x00066A0005000001, Slot 1, IOC 1";

RX_CSUM=TRUE;

HEARTBEAT=100; }

NOTE:

The IOCSTRING field is a literal, case-sensitive string. Its syntax must be exactly in the format shown in the previous example, including the placement of commas. To reduce the likelihood of syntax error, use the command Note that the chassis serial number must match the chassis Ox (Hex) value. The slot serial number is specific to the line card as well.

Each CREATE block must specify a unique NAME. The NAME represents the Ethernet interface name that will be registered with the Linux operating system.

IOCSTRING="Chassis 0x00066A00010003F2, Slot 1, IOC 1"; }

4. Create VirtualNIC interface configuration files. For each Ethernet interface defined in the /etc/sysconfig/qlgc_vnic.cfg file, create an interface configuration file, /etc/sysconfig/network-scripts/ifcfg-<NAME> (or /etc/sysconfig/network/ifcfg-<NAME> on Linux 2.6 kernels), where <NAME> is the value of the NAME field specified in the CREATE block.

Following is an example of ifcfg-eiocx setup for Red Hat systems:

5. Start the QLogic VNIC driver and the QLogic VNIC interfaces. Once you have created a configuration file, you can start the VNIC driver and create the VNIC interfaces specified in the configuration file by running the following command (as root):

# /etc/init.d/qlgc_vnic start

You can stop the VNIC driver and bring down the VNIC interfaces by running the following command:

# /etc/init.d/qlgc_vnic stop

To restart the QLogic VNIC driver, run the following command:

# /etc/init.d/qlgc_vnic restart

If you have not started the InfiniBand network stack (InfiniPath or OFED), then running the the InfiniBand network stack, since the QLogic VNIC service requires the InfiniBand stack.

Correct stopping order is:

 Stop QLogic VNIC service.  Stop the InfiniBand stack.

For example, if you use InfiniPath, the correct stopping order is:

If you try to stop the InfiniBand stack when the QLogic VNIC service is running, an error message displays, indicating that some of the modules of the InfiniBand stack are in use by the QLogic VNIC service. Also, any QLogic VNIC interfaces that you created are removed (because stopping the InfiniBand network stack unloads the HCA driver, which is required for the VNIC interfaces to be present).

If you want to restart the QLogic VNIC interfaces, run the following command:

# /etc/init.d/qlgc_vnic restart

You can get information about the QLogic VNIC interfaces by using the following script (as root):

# ib_qlgc_vnic_info

This information is collected from the /sys/class/infiniband_qlgc_vnic/interfaces/ directory, under which there is a separate directory corresponding to each VNIC interface.

VNIC interfaces can be deleted by writing the name of the interface to the /sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic file. For example, to delete interface veth0, run the following command (as root):

# echo -n veth0 > /sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic

More information for configuration, starting and stopping the interface, and basic troubleshooting is found in the QLogic OFED+ User Guide.

MPI over uDAPL

Intel MPI can be run over uDAPL, which uses IB Verbs. uDAPL is the user mode version of the Direct Access Provider Library (DAPL), and is provided as a part of

the OFED packages. You will also have to have IPoIB configured.

Setup for Intel MPI is described below.

1. Make sure that DAPL 1.2 (not version 2.0) is installed on every node. In this release they are called compat-dapl. (Both versions are supplied with the OpenFabrics RPMs.) They can be installed either with the Installer with the QLogicIB-Basic package or with rpm with the QLogic OFED 1.4 RPM set. They look something like this:

3. On every node, type the following command (as root):

# modprobe rdma_ucm

To ensure that the module is loaded whenever the driver is loaded, add RDMA_UCM_LOAD=yes to the that rdma_cm is also used, but it is loaded automatically.)

4. Bring up an IPoIB interface on every node, eg. ib0. See the instructions for configuring IPoIB for more details.

Managing the InfiniPath Driver

NOTE:

To use 4K MTU, set the switch to have the same 4K default. If you are using QLogic switches the following will apply:

For the Externally Managed 9024, use 4.2.2.0.3 firmware (9024DDR4KMTU_firmware.emfw) for the 9024 EM. This has the 4K MTU default, for use on fabrics where 4K MTU is required. If 4K MTU support is not required, then the 4.2.2.0.2 DDR *.emfw file should be used for DDR externally-managed switches. Use FastFabric to load the firmware on all the 9024s on the fabric.

For the 9000 Chassis, use the most recent 9000 code 4.2.4.0.1. The 4K MTU support is in 9000 Chassis version 4.2.1.0.2 and later. For the 9000 chassis, when the FastFabric 4.3 (or later) chassis setup tool is used, the user is asked what MTU they want. FastFabric (FF) can then set that MTU in all the 9000 Internally managed switches. The change will take effect on next reboot. Alternatively, for the Internally Managed 9000s, the ismChassisSetMtu command-line interface (CLI) command can be used. This should be executed on every switch and both hemispheres of the 9240s.

For reference, see the FastFabric Users Guide Version 4.3 and the SIlverStorm 9000 CLI Reference Guide Version 4.2. Both are available from the QLogic web site.

For other switches, see the vendors’ documentation.

Managing the InfiniPath Driver

The startup script for ib_ipath is installed automatically as part of the software installation, and normally does not need to be changed. It runs as a

system service.

The primary configuration file for the InfiniPath driver ib_ipath and other modules and associated daemons, is:

/etc/infiniband/openib.conf

Normally, this configuration file is set up correctly at installation and the drivers are loaded automatically during system boot once the RPMs have been installed. However, the ib_ipath driver has several configuration variables that set reserved buffers for the software, define events to create trace records, and set the debug level.

If you are upgrading, your existing configuration files will not be overwritten.

Configure InfiniPath Driver State

Use the following commands to check or configure the state. These methods will not reboot the system.

To check the configuration state, use this command. You do not need to be root:

$ chkconfig --list openibd

To enable the driver, use the command (as root):

# chkconfig openibd on 2345

To disable the driver on the next system boot, use the command (as root):

# chkconfig openibd off

NOTE:

This command does not stop and unload the driver if the driver is already loaded.

Start, Stop or Restart InfiniPath

Restart the software if you install a new InfiniPath release, change driver options, or do manual testing.

You can start, stop, or restart (as root) the InfiniPath support with:

# /etc/init.d/openibd [start | stop | restart]

This method will not reboot the system. The following set of commands shows how to use this script. Note the following:

# /etc/init.d/opensmd stop

# /etc/init.d/openibd restart

# /etc/init.d/opensmd start

NOTE:

Stopping or restarting openibd terminates any QLogic MPI processes, as well as any OpenFabrics processes that are running at the time.

openibd stop

openibd start

You can check to see if opensmd is running by using the following command (as root); if there is no output, opensmd is not configured to run:

# /sbin/chkconfig --list opensmd | grep -w on

When you need to determine which InfiniPath and OpenFabrics modules are running, use the following command. You do not need to be root:

$ lsmod | egrep ’ipath_|ib_|rdma_|findex’

Unloading the Driver/Modules Manually

You can also unload the driver/modules manually without using

/etc/init.d/openibd. Use the following series of commands (as root):

# umount /ipathfs

# fuser -k /dev/ipath* /dev/infiniband/*

7 Installation Verification and

Additional Settings

This section provides instructions for verifying that the software has been properly installed and that the drivers are loaded, and the fabric is active and ready to use. Information on adapter performance tuning is also provided.

LED Link and Data Indicators

The LEDs function as link and data indicators once the InfiniPath software has been installed, the driver has been loaded, and the fabric is being actively managed by a subnet manager.

Adapter and Other Settings

The following settings can be adjusted for better performance.

 Use taskset to tune CPU affinity on Opteron systems with the

QLE7240, QLE7280, and QLE7140. Latency will be slightly lower for the

Opteron socket that is closest to the PCI Express bridge. On some chipsets, bandwidth may be higher on this socket. See the QLogic HCA and QLogic OFED Software Users Guide for more information on using taskset. Also see the taskset(1) man page.

 On the switch use an IB MTU of 4096 bytes instead of 2048 bytes, if

available, with the QLE7240, QLE7280, and QLE7140. 4K MTU is

enabled in the InfiniPath driver by default. To change this setting for the driver, see “Other Configuration: Changing the MTU Size” on page 6-14.

 Use a PCIe Max Read Request size of at least 512 bytes with the

QLE7240 and QLE7280. QLE7240 and QLE7280 adapters can support

sizes from 128 bytes to 4096 bytes in powers of two. This value is typically set in the BIOS.

 Use PCIe Max Payload size of 256, where available, with the QLE7240

and QLE7280. The QLE7240 and QLE7280 adapters can support 128, 256,

or 512 bytes. This value is typically set by the BIOS as the minimum value supported both by the PCIe card and the PCIe root complex.

 Make sure that write combining is enabled. The x86 Page Attribute Table

(PAT) mechanism that allocates write-combining (WC) mappings for the PIO buffers has been added and is now the default. If PAT is unavailable or PAT initialization fails for some reason, the code will generate a message in the log and fall back to the MTRR mechanism. See BWrite Combining for more information.

 Check the PCIe bus width. If slots have a smaller electrical width than

mechanical width, lower than expected performance may occur. Use this command to check PCIe Bus width:

$ ipath_control -iv

This will also show link speed.

Customer Acceptance Utility

ipath_checkout is a bash script that verifies that the installation is correct and

that all the nodes of the network are functioning and mutually connected by the InfiniPath fabric. It must be run on a front end node, and requires specification of a nodefile. For example:

$ ipath_checkout [options] nodefile

The nodefile lists the hostnames of the nodes of the cluster, one hostname per line. The format of

hostname1

hostname2

...

NOTE:

The hostnames in the nodefile are Ethernet hostnames, not IPv4 addresses.

NOTE:

To create a nodefile you can use the ibhosts program. It will generate a list of available nodes that are already connected to the switch. The
